Iracing

iRacing.com is an online, subscription-based motor racing simulation service for Microsoft Windows, Linux and OS X created by iRacing.com Motorsport Simulations. In addition to accurately modeled vehicles and tracks, iRacing provides servers on which to race, to practice, and utilises a sanctioning body to organize and oversee competition within the service.

From the start, iRacing has been marketed as both an entertainment service and a training tool for real life racers.[1] They have established numerous partnerships with real-world racing organizations and series, including NASCAR, IndyCar, V8 Supercars, the SCCA, the Skip Barber Racing School, the Volkswagen Jetta TDI Cup, the new Formula Renault 2.0, the Star Mazda Championship, the Blancpain Endurance Series and McLaren F1 among others.[2][3]

The service was launched to the public on August 26, 2008. There were over 50,000 active members as of December 2013, and over 55,000 by late May 2015.[
